Remove All Missing Links with frames

How can I make a script to remove all missing links with frames In indesign?

var doc = app.activeDocument;
var links = doc.links;

for (var i = links.length-1; i >= 0; i--) {
if (links[i].status == LinkStatus.LINK_MISSING) {
  try {
   links[i].parent.remove();
             var image = link.parent;
          var frame = image.parent;
          frame.remove();
          counter++;

  }
  catch (err) {
   $.writeln(i + " - " + err);
  }
}
}

I try this script, but still remain a frame, what's wrong with that?
